Stop Wondering How to Fix Your Sourdough Starter!

If you’ve ever made sourdough bread, you know that sourdough starter is a crucial ingredient. It’s what gives the bread its signature tangy flavor and chewy texture. However, sometimes your sourdough starter might start to smell like alcohol, which can be concerning. In this article, we’ll explore why sourdough starter smells like alcohol and whether it needs to be fixed or not.

This post is all about ‘why does my sourdough starter smell like alcohol?’

A sourdough starter is essentially a mixture of flour and water that has been left to ferment. During the fermentation process, naturally occurring yeasts and bacteria feed on the sugars in the flour and produce carbon dioxide and alcohol. The carbon dioxide is what makes the bread rise, while the alcohol can give the starter a boozy aroma. But why does this happen, and is it a cause for concern? We’ll answer those questions and more in the following sections.

Key Takeaways

  • Sourdough starters are a mixture of flour and water that have been left to ferment.
  • The alcohol smell in sourdough starter is a natural byproduct of the fermentation process.
  • To fix a sourdough starter that smells like alcohol, you can adjust its hydration level, feed it more often, or store it at a different temperature.

Why I Now Only Eat Sourdough Bread

There are quite a few reasons why I now only eat sourdough bread. For years, I’ve been strictly gluten free for health reasons since 2009. Not at all because of some fad because all the sweets I love are definitely not something I can eat anymore. Going gluten free hasn’t been as negative as I thought it was going to be. It helped me clean up my diet more than I realized was going to happen. Not only did I cut out gluten, but since I had to pay attention to ingredients, I became aware of all the junk that’s put in a lot of food. So in our house we avoid ingredients like high fructose corn syrup, corn syrup, and other processed stuff. 

A few years ago, I looked into sourdough and decided to give it a go. Although it’s not gluten free (although you can make it gluten free), the fermentation process makes it more digestible. It is easier on the gut for those who have an intolerance. 

For anyone who has Celiac Disease, you’ll still need to steer clear of regular sourdough bread. I don’t have a gluten free sourdough starter but hope at some point to figure out something to share with all of you!

Understanding Sourdough Starters

If you’re new to sourdough baking, you might be wondering what a sourdough starter is and how it works. In simple terms, a sourdough starter is a mixture of flour and water that has been left to ferment. The fermentation process is what gives sourdough bread its distinct flavor and texture. 

Composition of a Sourdough Starter

A sourdough starter is made up of two main components: yeast and bacteria. The yeast in a sourdough starter is a wild strain, known as wild yeast, that is naturally present in the flour. The bacteria in a sourdough starter is a strain of lactic acid bacteria that is also naturally present in the flour. The yeast and bacteria work together to ferment the flour and water mixture, producing carbon dioxide gas and organic acids. Their success and growth is dependent on temperature, hydration, and the activity of the yeast and bacteria as a result.

For reference, the temperature for sourdough starter should always be between 75 to 85 degrees Fahrenheit.

Fermentation Process

The fermentation process is what sets sourdough bread apart from other types of bread. When you mix flour and water together and leave it to sit, the yeast and bacteria in the mixture start to feed on the carbohydrates in the flour. As they do, they produce carbon dioxide gas and organic acids. The carbon dioxide gas is what causes the bread to rise, while the organic acids give the bread its distinct sour flavor.

As the fermentation process continues, the yeast and bacteria in the sourdough starter multiply and become more active. This is why it’s important to feed your sourdough starter regularly. If you don’t feed it often enough, the yeast and bacteria will run out of food and the fermentation process will slow down or stop altogether.

Why Does My Sourdough Starter Smell Like Alcohol

If you’re new to sourdough baking, you might be surprised to find that your sourdough starter smells like alcohol. Actually, you may come across all different kinds of smells and appearances from your starter. The smell of alcohol is a common issue that many bakers face, and it’s not necessarily a cause for concern. In this section, we’ll explore why sourdough starters smell like alcohol and what you can do about it.

Alcohol Production in Fermentation

The primary reason for sourdough starter smelling like alcohol is because it’s not being fed enough. If it’s not being fed enough or you’ve skipped feedings, the starter will start producing this smell. You may even notice a dark liquid forming on top. This dark liquid is harmless and known as hooch. It’s a natural occurring alcohol and is signaling that the starter is hungry.

How Often Should the Starter Be Fed

If you have a mature sourdough starter, it should be fed at least once a day if you’re leaving it out on the counter. If you’re not frequently baking, my suggestion is not to keep it on the counter. Instead, feed your starter, put a lid on the jar, and pop it in the fridge. The cold temperature in the fridge slows down the fermentation process and you’ll only need to feed it once a week instead of every day. Sourdough starters can still show signs of hunger even if it’s in the fridge and they will still form hooch.

Let’s take a look for any signs that may indicate that your starter is hungry. 

Signs of hunger besides the hooch are:

  • Inactivity of the starter – the starter isn’t bubbling and active. It’s smooth with no bubbles in it.
  • It has a thick layer forming on top and smells either like alcohol or pungent. It doesn’t smell yeasty and pleasant like it normally does.
  • It’s no longer rising. It was rising, reached its peak, and has deflated.
  • It’s not rising at all. You fed it but it hasn’t risen. It needs another feeding in less than 24 hours.

Assessing Sourdough Starter Health

If you’re new to sourdough baking, you may be wondering how to tell if your sourdough starter is healthy. A healthy sourdough starter should have a tangy aroma, a bubbly texture, and a slightly acidic taste. Here are some indicators to help you assess the health of your sourdough starter.

Ideal Sourdough Starter Smell

A sourdough starter should have a pleasant, tangy aroma. The smell can vary depending on the type of flour you use, but it should never smell like alcohol or acetone. It should also smell kind of yeasty. 

Preventing Sourdough Starter Problems

If you’re experiencing problems with your sourdough starter smelling like alcohol, there are a few things you can do to prevent this issue from occurring.

Routine Maintenance Tips

Firstly, it’s important to maintain your sourdough starter regularly. This means feeding it on a regular schedule, ideally once per day. By doing this, you’re ensuring that the bacteria in the starter are well-fed and active, which can help prevent the development of off flavors and smells.

Secondly, make sure you’re storing your sourdough starter at an appropriate temperature. The average temperature your sourdough starter should be stored is 75°F. If you store your starter at a higher temperature, then the bacteria will become more active and hungrier, which can lead to the production of more alcohol and acetic acid. On the other hand, if you store your starter at a lower temperature, it will slow down the fermentation process and cause your starter to become sluggish.

Finally, make sure you’re using the right type of flour to feed your starter. Whole wheat flour, for example, can lead to a more sour flavor, while all-purpose flour can lead to a milder flavor. Experiment with different types of flour to find the flavor that you like best.

Common Mistakes to Avoid

There are a few common mistakes that people make when working with sourdough starter that can lead to off flavors and smells. Here are a few things to avoid:

  • Letting your sourdough starter sit for too long without feeding it. This can cause the bacteria to become stressed and produce off flavors and smells.
  • Using chlorinated tap water to feed your starter. Chlorine can kill the bacteria in your starter, so it’s best to use filtered or bottled water instead.
  • Not measuring your ingredients carefully. It’s important to measure your flour and water carefully when feeding your starter to ensure that it has the right consistency.
  • Not discarding enough of your starter when feeding it. If you don’t discard enough of your starter, it can become too acidic and develop off flavors and smells.

By following these tips and avoiding common mistakes, you can help prevent your sourdough starter from developing off flavors and smells.

Frequently Asked Questions

What does a healthy sourdough starter typically smell like?

A healthy sourdough starter typically smells sour, yeasty, and slightly tangy. The smell can vary depending on the type of flour used and the temperature at which the starter is kept. Some people describe the smell as similar to that of freshly baked bread or beer. If your starter smells like this, then it is a good sign that it is healthy and active.

Is an alcoholic smell from my sourdough starter a sign of spoilage?

No, an alcoholic smell from your sourdough starter is not necessarily a sign of spoilage. In fact, it is quite common for sourdough starters to emit an alcoholic odor, especially if they are hungry and in need of feeding. The smell is caused by the production of ethanol during fermentation, which is a natural byproduct of the yeast and bacteria in the starter.

How can I tell if my sourdough starter has gone bad?

If your sourdough starter has gone bad, it will have a foul odor and may have a discolored appearance. Signs of spoilage include a putrid smell, mold growth, or a slimy texture. If your starter has any of these signs, it is best to discard it and start over.

What should I do if my sourdough starter smells like vinegar?

If your sourdough starter smells like vinegar, it is a sign that it has become too acidic. This can happen if the starter is left too long without feeding or if it is kept at a warm temperature. To fix this, you can discard some of the starter and feed it with fresh flour and water. You may need to repeat this process a few times to restore the pH balance of the starter.

Can a sourdough starter with a sour milk odor still be used for baking?

If your sourdough starter has a sour milk odor, it may still be usable for baking. This smell can be caused by the production of lactic acid during fermentation, which is a natural process in sourdough starter. However, if the smell is overpowering or accompanied by other signs of spoilage, it is best to discard the starter and start over.

Why does my sourdough starter have a strong acetone-like aroma?

A strong acetone-like aroma from your sourdough starter is a sign that it is hungry and in need of feeding. This smell is caused by the production of acetic acid during fermentation, which is a natural byproduct of the bacteria in the starter. To fix this, you can discard some of the starter and feed it with fresh flour and water.
